Weighted Decomposition Estimates for Differential Forms
Journal of Inequalities and Applications, 2010 After introducing the definition of Ar,λβ-weights, we establish the Ar(Ω)-weighted decomposition estimates and Ar,λβ(Ω)-weighted Caccioppoli-type estimates for A-harmonic tensors.

Estimating GVAR weight matrices [PDF]
Spatial Economic Analysis, 2013 The objective of this paper is to illustrate how the weights that are needed to construct foreign variable vectors in global vector autoregressive (GVAR) models can be estimated jointly with the GVAR’s parameters. An application to real gross domestic product (GDP) growth and inflation as well as a controlled Monte Carlo simulation serve to highlight ...

A short proof of commutator estimates [PDF]
, 2018 The goal of this note is to give, at least for a restricted range of indices, a short proof of homogeneous commutator estimates for fractional derivatives of a product, using classical tools.

Scaling-sharp dispersive estimates for the Korteweg-de Vries group [PDF]
, 2008 We prove weighted estimates on the linear KdV group, which are scaling sharp. This kind of estimates are in the spirit of that used to prove small data scattering for the generalized KdV equations.Comment: 5 ...

On the complexity of computing Gr\"obner bases for weighted homogeneous systems [PDF]
, 2015 Solving polynomial systems arising from applications is frequently made easier by the structure of the systems. Weighted homogeneity (or quasi-homogeneity) is one example of such a structure: given a system of weights $W=(w\_{1},\dots,w\_{n})$, $W ...

Weighted Cheeger constant and first eigenvalue lower bound estimates on smooth metric measure spaces
Advances in Difference Equations, 2021 We establish new eigenvalue inequalities in terms of the weighted Cheeger constant for drifting p-Laplacian on smooth metric measure spaces with or without boundary.

Generalized and weighted Strichartz estimates
, 2011 In this paper, we explore the relations between different kinds of Strichartz estimates and give new estimates in Euclidean space $\mathbb{R}^n$. In particular, we prove the generalized and weighted Strichartz estimates for a large class of dispersive ...

Space-time decay rate for the 3D compressible quantum magnetohydrodynamic model
Electronic Research ArchiveThis paper investigates the space-time decay properties of solutions to the three-dimensional compressible quantum magnetohydrodynamic (QMHD) model. By employing weighted Sobolev space techniques, we establish the optimal decay rate for the $ k $-th ...
